CONVEYER FOR COKE OR ANALOGOUS MATERIALS.

SPECIFICATION forming part of Letters Patent No. 582,903, dated May 18,1897.

Application filed February 6, 1897. Serial No. 622,340- (No model.)

To ally/ham it may concern.-

Be it known that I, JAMES M. DODGE, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Conveyers for Coke or Analogous Materials, of which thefollowing is a I specification.

The object of my invention is to provide means for conveying and coolingcoke and like material and at the same time prevent the warping of thebuckets and pans in which the material is conveyed.

In the accompanying drawings, Figure l is a longitudinal sectional viewof a conveyer, illustrating my invention. Fig. 2 is a view of anotherform of conveyer, and Fig. 3 is a view showing the buckets withdrainageopenings.

l-Ieretofore it has been almost impossible to convey coke directly fromthe retorts, except by the hand process, owing to the fact that the heatof the coke soon distorts the buckets or pans and makes the workingparts of the conveyer useless in a very short time, and, furthermore,the coke conveyed to a pile without being sprayed by water will soonburn away until it is practically destroyed.

By my invention I am enabled to convey the coke directly from theretorts and at the same time quench the fire immediately and deliver thecoke at the end of the conveyer in a cooled condition and withoutdistorting the buckets or pans.

Referring to Fig. 1, A is an endless-chain conveyer consisting in thepresent instance of two chains having buckets a mounted between them,the buckets being secured to the links. The chains pass around wheels BB at each end. One of the wheels may be the driving-wheel. It will beunderstood, however, that the conveyer or buckets may be modifiedWithout departing from my invention. The bottoms of the buckets arepreferably Water-tight, so as to hold sufficient water for the purposedescribed hereinafter.

O is a chute which extends over the conveyer and is so situated thatwhen the coke is drawn from the retorts it can be discharged into thechute and the chute in turn will discharge into the buckets of theconveyer. There can be arranged alongthe conveyer a series of thesechutes, if necessary, in front of the retorts, and a chute can beprovided with mechanism by which the material can be fed to the conveyerin given quantities.

E is a chute at the opposite end of the conveyer, onto which the coke isdischarged and from which it may pass to a pile or to another conveyerof any of the common forms, by which it is carried to the bins, cars, orboats.

Directly back of the chute O is a water-pipe d, provided with a suitablevalve, and this pipe discharges into the buckets of theconveyer, and thedischarge is so regulated that during the travel of each bucket underthe outlet of the pipe a certain amount of water Will flow into thebucket, so that when the bucket passes under the chute C to be chargedWith coke the hot coke will be deposited in the bucket containing thewater, and the heat of the coke will immediately tend to vaporize thewater, and the water at the same time will cool the coke, so that as theconveyerbucket moves forward the coke will be gradually cooled and thewater will be gradually vaporized until the bucket reaches the point ofdischarge w, when the coke Will be comparatively cool and the water willbe vaporized, so that the coke is not destroyed by the slow burningprocess, as the fire is quenched immediately, and as the buckets containwater when first charged with the coke they do not warp, andconsequently the machinery is not impaired by the handling of the heatedmaterial.

It will be understood that my invention may be used for conveying otherheated material than coke which is not injured by plunging it into abody of water or other liquid.

In Fig. 2 I have shown a bucket-elevator A, the boot D of which forms areservoir for water or other liquid, and above this boot at one side isthe feed-chute C for the coke, so that as the buckets pass around thelower guide-wheel they enter the water and scoop 5 up a certain amount,and as they pass the feed-chute they will be charged with coke, whichwill be cooled by. the water in the buckets.

In order to regulate the amount of water in the buckets,drainage-openings may be formed therein, as shown in Fig.3, so thatacertain amount of water will escape when the buckets are charged withcoke, and when the flow of water is irregular a pan or gutter I maybearranged under the buckets to receive the escaping water.

I claim as my invention 1. The combination in apparatus for conveyingcoke and like material, of the conveyer, having buckets, a chute adaptedto direct the heated coke into the buckets of the conveyor, with awater-supply so situated that the buckets will be charged with waterprior to being charged with the heated coke, substantially as described.

2. The combination in an endless-chain conveyor having buckets adaptedto travel in a horizontal plane, a pipe for admitting water to thebuckets, a spout for dischargingheated coke into the buckets after theyare partially filled with water, substantially as described.

3. The combination in an endless-chain eonveyer having buckets, a chuteadapted to direct the heated coke into the buckets of the conveyer and awater supply adapted to charge the buckets with water in advance of thechute, the conveyer being so proportioned that prior to the discharge ofthe coke from the buckets the water will be vaporized, sub stantially asdescribed.

ii. The combination in an endless-chain conveyor having buckets adaptedto travel in a horizontal plane, a pipe for admitting water to thebuckets, a spent for discharging heated coke into the buckets after theyare partially filled with water, and a dischargespout at the end of theconveyor, the conveyer being of such a capacity and being driven at sucha speed that the water willbe vaporized before the coke is dischargedfrom the e011- veyer, substantially as described.

5. The combination of an endless-chain conveyor having buckets thereonwith drainage-openings, a chute for coke, and a watersupply in advanceof the coke-chute so that water will be admitted to each bucket prior toits being charged with coke, the surplus water escaping through thedrainage-openings, substantially as described.

6. The combination of an endless-chain convcyer having buckets thereonwith drainage-openings, a charging-chute, a water-supply in advance ofthe charging-chute so that each bucket will be supplied with water priorto being charged with coke or other material, and a pan or guttermounted under the buckets and adapted to receive the surplus waterescaping from the buckets, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
